Why the study?
What are the 20-year secular trends in the incidence, treatment, and outcomes of severe aortic stenosis?
What are the 20-year secular trends in the incidence, treatment, and outcomes of severe aortic stenosis?
Despite increased utilization of aortic valve replacement over 20 years, substantial undertreatment and unchanged lethality in severe aortic stenosis highlight critical gaps in current management pathways.
Undertreatment and stable lethality in severe AS persist despite more AVR; supports hypothesis-generating need for better pathways before changing practice.
Over 20 years, the population incidence of severe AS remained stable with increased absolute case burden related to population growth. Despite stable severe AS presentation, AVR performance grew notably, but while declining, undertreatment remained substantial and disease lethality did not yet decline. These population-based findings have important implications for improving AS management pathways.
